The NL240 is a wireless networking peripheral that provides Wi-Fi connectivity to our dataloggers and peripheral devices over standard 802.11b/g/n networks. It is a low-power device that offers unique and powerful PakBus networking capabilities, but it is easy to configure. The NL240 provides direct access to all the IP capabilities of the CR800, CR1000, and CR3000 dataloggers.
The NL240 can take advantage of the thousands of Wi-Fi hotspots available in cafés, universities, hotels, and airports. Wi-Fi also provides encryption to protect traffic and uses a global set of standards so the same device can be used internationally.
The NL240 is an industrial device that goes beyond the typical Wi-Fi serial device server. It supports Wi-Fi communication with an iOS or Android device when used with our LoggerLink apps. By providing direct access to all the IP capabilities of the CR800, CR1000, and CR3000 dataloggers, the NL240 provides:

Wi-Fi ad hoc networking is provided for the purpose of networking between NL240 interfaces. Ad hoc networking is supported by iOS, allowing an iOS device to connect to an NL240 that has created a network. Wi-Fi ad hoc networking is not supported natively by Android OS and is difficult to support on Windows 7 and greater.
Our Device Configuration Utility must be version 2.03 or higher.
|Data Logger||Serial Server||PakBus Router||Bridge Mode*|
♣The CR300 connects to the NL240 using a 10873 serial cable that is not supplied with the CR300 or the NL240. The CR300-series dataloggers are not compatible with the bridge mode functionality in the NL240 interface.
* The data logger OS must be OS 25 or higher for bridge mode applications.
** It is possible to use an NL240 to connect to a mixed-array data logger (e.g., CR10, CR10X, CR23X, 21X, CR7) by using an SC32B between the data logger's CS I/O port and the NL240's RS-232 port.
Windows USB drivers for the NL240 are installed via the Device Configuration Utililty. In the Device Configuration Utility, click on the link "install the device driver for the NL240" in the main body of text for the NL240.
Note: Drivers must be installed before connecting the NL240 to your computer.
Current NL240 firmware. Requires the Device Configuration Utility and a USB micro cable.
Note: When updating to OS 10.03 from OS 6 or previous, settings will be reinitialized to factory defaults. When updating to OS 10.03 from OS 7, settings will be retained.

No. Antennas are ordered separately, allowing customers to choose the best antenna for their application and site.
If the NL240 is on a different network from the server running LoggerNet, either the station or LoggerNet needs to be able to initiate a connection to the other:
It depends on the application, funds available for new hardware, and the quantity of data that will be collected. Viable options include the NL240, RF4xx spread-spectrum-series radios, RF32x UHF/VHF radios, and cellular modems.
Connect one data logger to the RS-232 port (6784) and the other data logger to the CS I/O port (6783). To access a data logger on the RS-232 port, use the IP address xxx.xxx.xxx.xxx:6784. To access a data logger on the CS I/O port, use xxx.xxx.xxx.xxx:6783. For setup instructions and configuration assistance, refer to the NL240 instruction manual, use the LoggerNet Network Planner tool, or contact Campbell Scientific.
Yes. The NL240 wireless network link was designed for this purpose.
The NL201 and NL240 are powered via the DC barrel connector and/or the CS I/O port. Sometimes, users who are using the network link
interface as a serial terminal server, PakBus router, or Modbus gateway want to connect their devices via the CS I/O port while
providing power only through the DC barrel connector and a 12 V source (such as a data logger SW12V output). In this scenario, a jumper
inside the NL201 or NL240 can be removed, preventing the interfaces from always being powered by the CS I/O connections. For more
information, refer to the instruction manual for the interface.
The NL200-series of devices can be set to bridge the Ethernet or Wi-Fi interface and the CS I/O interface. All packets that come into the device via Ethernet or Wi-Fi will be transferred to the data logger over the CS I/O port. This enables the data logger to make all of its IP-related services available. Configuring an NL200-series device with bridge mode enabled is analogous to adding a native Ethernet or Wi-Fi port to the data logger. Bridge mode does not use PPP.
No, it is not.
Yes. We currently have, and continue to develop, a variety of products that are compatible with IPv6 networking. For example, the NL200/201 and NL240 can serve as IPv6 serial servers for our data loggers and communications peripherals. We anticipate IPv6 compatibility to be included in the CR800, CR850, CR1000, and CR3000 by mid-2014.
